Kevin McCloud's Listed Britain.

Kevin will travel the length and breadth of the country to uncover the stories behind some of Britain’s most remarkable buildings and structures, exploring why places as diverse as Coventry Cathedral and the Penguin Pool at London Zoo have been judged worthy of the highest level of protection. This is heritage with the doors thrown open, as Kevin is invited into parts of these structures the public never normally sees, as he meets the people who care for them and gets hands-on himself.
